A sea of more than 100 fundraisers will come together on Hunstanton beach this weekend.
The running event, Beat the Tide, is due to take place on Sunday.
Participants will aim to complete in the 10k run along Hunstanton’s beach, or families and children can opt for a 5k fun run.
Both races will be to raise money for the Stroke Association.
Mike Ennis, 71, is taking part in the 10k event.
His wife Carole died at the age of 65 after suffering from three stokes and lung cancer.
She was treated at King’s Lynn’s Queen Elizabeth Hospital.
“The stroke unit is always short of equipment. Through Friends of the Stroke Unit we have given £10,000 to the Transient Ischaemic Attack (TIA) clinic.”
The TIA clinic is for patients who suffer a mini-stroke.
But despite being over 70, Mr Ellis has no qualms about running the race.
After his wife died five years ago, he started to run to help cope with the grief.
He said: “I have raced the Grand East Anglia Run before and I am a member of the Ryston Runners so I train a lot.
“I think my wife would be proud of what I’m doing,” he said.
George Burroughs, fundraising manager from the Stroke Association in the East of England, said: “There are around 152,000 strokes a year in the UK – that’s one every three and a half minutes.
“The Beat the Tide is a great opportunity for stroke survivors, volunteers and carers to all come together to help conquer stroke.” For more information about stroke, visit www.stroke.org.uk.
